Phys.org / Football-sized fossil creature may have been one of the first land animals to eat plants

Life on Earth started in the oceans. Sometime around 475 million years ago, plants began making their way from the water onto the land, and it took another 100 million years for the first animals with backbones to join them. ...

Phys.org / Webb unveils nature of distant ultraviolet-luminous galaxy CEERS2-588

Astronomers from the University of Tokyo in Japan and elsewhere have employed the James Webb Space Telescope (JWST) to observe a distant ultraviolet-luminous galaxy known as CEERS2-588. Results of the observational campaign, ...

Phys.org / Nature's 'engine is grinding to a halt' as climate change gains pace, says study

Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats ...

Phys.org / Trump to undo legal basis for US climate rules

President Donald Trump is poised Thursday to revoke a landmark scientific finding that greenhouse gases endanger public health by driving climate change—a determination that underpins US regulations aimed at curbing planet-warming ...

Phys.org / Experiment relies on pulsars to probe dark matter waves

Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...

Phys.org / Only humans have chins: Study shows it's an evolutionary accident

Dashiell Hammett mentioned Sam Spade's jutting chin in the opening sentence of his novel, "The Maltese Falcon." Spade's chin was among the facial features Hammett used to describe his fictional detective's appearance, but ...

Phys.org / Promise the Earth: Why real climate action means restraint

A new book by a Cambridge engineer and an Oxford theologian argues that our faith in technology to solve the climate crisis is distracting us from the uncomfortable truth: that saving the planet is neither a task for future ...

Phys.org / Pulsar timing hints at a nearby dark matter 'sub-halo'

A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti ...

Phys.org / The 'Little red dots' observed by Webb were direct-collapse black holes

The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the universe has evolved ...

Phys.org / Scientists discover 'levitating' time crystals that you can hold in your hand

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create commercial or industrial ...

Phys.org / New experiments suggest Earth's core contains up to 45 oceans' worth of hydrogen

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's suspected to be a major ...

Phys.org / Hurricane Helene did not shift US climate views or votes, study finds

Hurricane Helene, one of the deadliest hurricanes in US history, did not affect people's views on climate change or their intentions to vote for politicians advocating stricter climate policies. This is shown in a new study ...
